Research interests

My research focus is to investigate the different roles of RNA and understand how they are detected and modified. One essential RNA processing enzyme is the human tRNA ligase. It catalyzes the ligation of RNA ends during pre-tRNA splicing and during unconventional splicing of Xbp1 mRNA during stress responses. I want to gain insights into the molecular details of these reactions and investigate how the pathways are regulated. Additionally, I am part of the young independent researcher group bioSTAR (funded by the FWF). In this project, we aim to develop programmable chemical probes that are capable of sensing specific RNA sequences followed by a bioorthogonal reaction. As a first application we want to use them to target bacterial RNA sequences and test their potential as novel antibiotic drugs.
